Meet the Cast of 'Bon Appétit, Your Majesty,' Netflix's Latest Hit K-Drama

If you're a fan of period dramas that fill both your heart and your stomach (or if you're on your third rewatch of Mr. Queen), Bon Appétit, Your Majesty is your next must-watch K-drama. Based on the web comic Surviving as Yeonsangun’s Chef, the new genre-bending series follows a virtuoso cook who's magically transported from 2025 to the Joseon era when she comes upon a mysterious ancient cookbook called "Mangunrok." She lands in the crosshairs of one of Korean history's cruelest tyrants; lucky for her, the show's version is more misunderstood dreamboat than unrelenting despot.

Since its premiere on August 23, Bon Appétit, Your Majesty has become appointment viewing, earning the highest domestic ratings of any tvN drama this year and a firm spot in Netflix's Top 10 for non-English shows. With the romance K-drama airing weekly through September, it's time to learn more about the global superstars and acclaimed actors bringing the time-bending court intrigue to life. Below, learn everything you need to know about the cast of Bon Appétit, Your Majesty.

Lim Yoon-a as Yeon Ji-yeong

When we first meet Yeon Ji-yeong in 2025, she's an acclaimed chef who has just won the grandest cooking competition in France.

She has also starred in movies including the Confidential Assignment franchise, Exit, A Year-End Medley, and Pretty Crazy.

Lee Chae-min as King Yi-heon

Joseon's monarch Yi-heon is an erratic tyrant who's despised for his practice of abducting women and bringing them to the palace as "entertainers," known as "chaehong" (This is inspired by the real-life ruler Yeonsangun.) We soon learn that all his cruelty (including the chaehong) is part of his single-minded mission to get revenge for his mother's murder. As each of Ji-young's meals reminds him of his late mother, his heart starts to soften toward the cook.

Lee Chae-min, 24, has had a meteoric rise as an actor and TV personality since his debut in 2021.

Seven years ago, Kang Mok-ju was imprisoned for killing the nobleman who had bought her from her mother. Prince Je-san freed her and installed her as Yi-heon's junior consort, to aid in the prince's plots. When the mysterious Ji-yeong begins winning Yi-heon's favor, Mok-ju becomes determined to get her out of the picture.
